Subject: [PATCH 1/2] net: mvneta: remove bogus use of device_node.data ptr

From: Rob Herring <[email-masked]>
Date: Thu, 20 Jul 2017 09:27:10 -0500

Nothing sets ever sets data, so it is always NULL. Remove it as this is
the only user of data ptr in the whole kernel, and it is going to be
removed from struct device_node.

Probably there's a better fix here to actually enable the h/w buffer 
manager.

I intend to take this thru the DT tree as patch 2 is dependent on this.
